' Be it known that I, @I IARLEs BECK, a citizen of the United States, and resident of Rockvill e Center,1 county of Nassau, and State of New York, have invented certain new and useful Improvements in Tool- Cl'amps,.ofwhich' the following is a specification ity of tools may be securely held togetlrer{toform a compactand convenient package for storing in 'a tool box. I V Another objectoftheinventi'on is to provide a simple device ofthe class described by means of which a. series of wrenches, or

of the device with the clamp released; Fig.

3 an end view thereof showing the clamp in its locked position; Fig. 4 a plan view, the

locking device being in the position shown" in Fig. 2; Fig. 5 a side elevation of a slightly different form of the device; Fig. 6 a front elevation of the device shown in Fig. 5; and Fig. 7 a side elevation with the clamping device released.

Referring to the various parts by numerals, 1 designates a series of wrenches secured within the clamping device. The clamping device consists of a holding frame 2 bent to form the rectangular holding socket 3 having the long side arm 4:, and the opposite short side arm 5, said arms being connected by the wall 6. At the outer end of the short arm 5 an offset 7 is formed, and at the outer end of said oifset portion is an outwardly extending cam arm 8, said arm being bent outwardly to form the cam 9. The cam arm is apertured for the passage for the clamping bar 10, and the long arm 4 of the socket is correspondingly apertured to receive the end of the clamping bar. This arm is also formed with the radial slots 11 which extend outwardly from the margin of the aperture; and the clamp bar is provided at its The object of this invention is to provide" a simple device by means of whichfla plural?

end with radial pins 12' which are adapted to be passed throughthe slots 11, and serve to hold the clamp bar in position when said bar is partially rotated to carry said pins out of register with said slots. The outer end of the clamp bar is provided with a cross pin or bar 13 which serves the double purpose. of means forrotating the bar, and as. means for binding on the cam 9,v and thereby drawing the two arms of the clamp together.

In operation the series of wrenches or othertools are vplaced side by side in the rectangular socket 3, as illustrated in Fig. 1, and the innerendof the clamp rod is passed through the-aperture in the longarm 45 of" the socket. This brings one endof the cross pin 13 ag'ainst'the cam wall 8, and by a partial rotation of the said rod said pin will ride on the cam 9 and draw the two arms of the" clamp toward each other, there by securely clamping the wrenches or other tools within the rectangular socket 3. It will thus be seen thatby a slight turn of the clamping bar the wrenches maybe either locked in the socket to form a convenient package for storing in an automobile tool box, or they may be released from the socket, depending on the direction of rotation of the looking bar.

In Figs. 5, 6 and 7 is illustrated a slight variation in the'form of the means for drawing together the arms of the clamp. In these views the locking bar is provided at its inner end with a threaded portion 14: which is adapted to enter a correspondingly threaded aperture in the long arm 4 of the clamp. The locking bar 10 is provided with a head 15 which is adapted to bear against the portion 8 of the clamp, whereby when the rod is screwed into the arm 4? the said head 15 will draw the two arms of the clamp together.

By providing the offset portion 7 the looking pins 12 or the threaded portion 14 may be withdrawn from the path of the tools so that they may be freely removed from the socket. This offset portion also insures the clamping of the tools within the socket 3 as it stiflens one side of the clamp about midway the ends thereof, thus insuring the inward movement of the arm 5 under the influence of the clamping bar.

From the foregoing it is manifest that I provide a very simple and easily operated clamp in which the tools may be very quickly locked, or from which they may be almost instantly released. 7 a

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is: a.

1. A tool clamp comprising a holding frame formed witha socket and provided with side arms, one of said arms being ofl'set at the outer end of the socket and both of said arms being apertured beyond the socket, an exterior cam formed on one of thearms adjacent the perforation, a clamp rod extending through the perforations in the arms and provided with means adapted to interlock with both of said arms and to engage said cam to draw the two arms together.

2. A tool clamp comprising a holding frame bent to form a rectangular socket to receive a series of tools, the side arms of the.

adapted to engage the exterior cam to draw both of said arms being apertured beyond the ofiset portion of one of saidside arms,

'a clamp rod extendingthrough the perfora tions in the arms and provided with means adapted to engage both of said arms to draw-them toward each other, the end of said clamp rod being adapted to lie in the laterally offset portion of one of the side arms, when said rod is disconnectedfromsaid arms and the socket is opened. 4. A tool holder comprising a holding frame having two arms forming a socket, a clamping rod extendmg across between said side arms and connectmg them together,

means at both ends-ofsaid clamping rod to engage the side arms and a cam surface formed on oneof the side arms and adapted to be engagedby the clamping rod,' where-l by upon the rotation oftheclamping rod the side arms of the holding frame willbe drawn toward each other. A
